KEY MESSAGES

Issued at 107 PM CDT Fri Aug 21 2026

- Widespread heat across the area with potential expansion of heat headlines. Several areas expected to be 105-108 today and a degree or two warmer on Saturday continuing into Monday

- Isolated to widely scattered afternoon convection possible this afternoon and again on Saturday.

SHORT TERM

(This evening through Saturday night) Issued at 107 PM CDT Fri Aug 21 2026

Satellite imagery showing remnants of eastern OK MCS moving south- southeast towards the Arklatex. Outflow from this MCS and associated southeasterly winds are in western OK and some enhancement in the cu field is noted at this time just south of GAG. Surface obs showing westerly winds over the central and southern TX Panhandle while north-northwest winds are observed in the northern panhandle. Models showing that surface winds in our area are forecast to become southerly late this afternoon and as convective temps are reached a few isolated to widely scattered storms will be possible for a short time. Warm mid level temps and lack of shear will preclude any real storm organization although there could be some gusty winds as these storms collapse. On Saturday a similar situation can be expected although there will be a boundary oriented more northwest to southeast through the CWA. Widely scattered storms are expected in the late afternoon across this area. CAPE values will not be impressive, generally 750-1000 j/kg. However, inverted V profiles, DCAPE values over 1700 and temp-dwpt spreads of 50-60 degrees suggests strong winds would be the main threat with these storms.

The upper level high pressure and ridge continue to amplify and slowly shift east. This will lead to hot temps and heat headlines through the early portion of the weekend with temps of 105-109.

LONG TERM

(Sunday through next Thursday) Issued at 107 PM CDT Fri Aug 21 2026

High pressure ridge shifts slowly east and as such the hottest temperatures can be expected Saturday through Monday. A shortwave trough riding over the ridge by Monday will help temper the ridge and allow for more substantial convective development over the higher terrain in CO/NM. The steering pattern will be favorable for this activity to enter into the panhandle and therefore pops will increase.

AVIATION

(00Z TAFS) Issued at 547 PM CDT Fri Aug 21 2026

VFR conditions will prevail at all TAF sites over the next 24 hours. Winds will be light around 5 to 10 kts and out of south to southwest at KAMA, and more variable at KDHT and KGUY as nearby boundary has light and variable winds. Isolated storms in the central Panhandles, will likely avoid the terminals, but could result in brief amendments should a storm pop up, or move into the area.
